Liposuction of the chin and neck can often produce spectacular results in individuals with localized fat deposits with youthful skin. This technique has the advantage of limited incisions, short operative time, and a quick recovery. Liposuction relies on youthful skin with good skin elasticity which snaps back after removal of the fat deposits. Post-operative compression is essential for a smooth appearance. Liposuction, unfortunately, does not correct deeper fat pockets, loose skin, jowls, or muscle bands. If the fat in your neck is "hanging" then skin laxity may be at issue. Loose skin is best corrected with a neck lift. Neck lifts are combined with liposuction or sculpting of the fat, removal of jowls, and tightening of muscle and skin. I would recommend consulting with a Board-certified Plastic Surgeon. At the time of your consultation, you can discuss your concerns and after an examination, your surgeon can provide treatment options to meet your goals.
